Built for the 1900 World's Fair, just at the Place de la Concorde you will see two structures covered by domes of iron and glass known as the Petit Palais and the Grand Palais.
With its 240 metre-long façade (entered from Avenue Franklin Roosevelt), the Grand Palais is used for various exhibitions. Part of the building is the permanent site of the Palais de la Decouverte where recent scientific discoveries, interactive exhibits, some very good temporary exhibitions and a planetarium are displayed.
Where to find the Petit Palais
The Petit Palais, located across the street from the Grand Palais houses the Musee des Beaux-Arts de la Ville de Paris.
